Title: Rotary cutting machines
IPC: A24B7/10
Filed: 1935-03-27
Abstract: 455,917. Sharpening machine-cutters. LEGG, Ltd., R., and SCHREIBER, P. Q. R., Eagle Wharf Road, Hoxton, London. March 27, 1935, No. 9578. [Class 60] [See also Group I] The revolving knives 1 of a machine suitable for cutting tobacco are ground during operation by means arranged so that the plane of grinding XX is displaced from the plane of cut YY, the knife holders being given angular displacements to cause the knife edges to move from one plane to the other in order that the ground face 1<1> of the knives may make a clearance angle with the plane of cut. In the apparatus shown the knives 1 are held by clamping plates 14 to arms 12 pivotally mounted on pins 9 secured to a boss 5 on the rotating knife shaft 2. Cam arms 13, forming with the arms 12 double levers, carry rollers 17 engaging an annular cam track 18 so shaped that during rotation the arms 12 are oscillated on the pins 9 to bring the cutting edges of the knives into the plane YY for cutting and the plane XX for grinding, where they contact with a cup wheel 20. Springs 22 engage third lever arms 23 to maintain the rollers in contact with the cam. Specification 437,272 is referred to.

Abstract: 1,034,134. Change-speed gear; gearing elements. A. WINDMOLLER and M. GENNERICH, [trading as WINDMOLLER & HOLSCHER]. March 6, 1964 [March 9, 1963], No. 9629/64. Headings F2D and F2Q. In a change-speed gear for a tube cutting device of a sack or bag making machine having two power paths between an input shaft 6 and two elements 17, 22 of a planet gear the third element 24 of which is fast with an output shaft 23 and each power path has an idler 10 (or 14) carried by a cage 9 (or 13) rockable on a shaft 12 (or 15) parallel to the input shaft 6 and meshes pinions 7, 11 (or 8, 15) on the input and parallel shafts, the input shaft 6 carries not more than two pinions 7, 8 which are easily replaceable by pinions of different size to change the gear ratio. The pinions 7, 8 are clamped on to the end of the input shaft 6 by a pressure cup 39 and bolt 40. As shown, the planet gear is a bevel gear with side wheels 17, 22 respectively fast with and geared to the shafts 12, 16 but the planet gear may be a spur train. The cage 9 is axially fixed on the shaft 12 whilst the cage 13 is mounted on the hub of pinion 15 which may slide axially on the shaft 16 to permit the idler 14 to mesh pinion 7. When both idlers mesh pinion 7 the pinion 8 may be removed and the cup 39 replaced by a longer cup. Discs 33, 34 fast with the pinions 7, 8 and discs 36, 38 rotatable relative to the idlers 10, 14 have diameters equal to the pitch circles of the adjacent gear to facilitate correct meshing of the gears. A set of pinions interchangeable with the pinions 7, 8 may be provided to give a series of output speeds in arithmetic progression.

Title: Improvement in method of forming sponge rubber bodies
IPC: C08L21/00
Filed: 1927-04-11
Abstract: 273,223. Marks, E. C. R., (Featheredge Rubber Co.). April 11, 1927. Spongy indiarubber.-Long lengths of sponge rubber are produced by enclosing a suitable composition in a flexible enclosure, such as a fabric tube, adapted to allow the compound to expand therein during vulcanization. The composition mav be coated with soapstone or the iike if it is desired to remove the fabric, and after being enclosed may be formed into a coil and placed in a steam-chamber. In an alternative method a piece of cloth is folded over the extruded strip and the whole is drawn through a heated metal tube with a slot along one side through which the edges of the cloth protrude. As the composition swells, the cloth is drawn into the tube. The rate of drawing is such that the rubber is vulcanized during its passage through the tube.

Title: Continuous supply unit
Inventor: LAVIN JAMES VINCENT
IPC: H02J9/06
Filed: 1990-11-13
Abstract: An uninterruptible power supply provides internal connection to an auxiliary power to provide continuous device power without duplicating regulation and switching circuits. The power supply includes an AC to DC converter, a transformer and a switch applying DC power from converter to the transformer. A pulse width modulation control circuit assures a regulated output voltage while application of auxiliary power is controlled by a fixed time interval one-shot that assures a smooth transition to AC utility power upon resumption of such power following a failure. An auxiliary AC power output signal is maintained for a video monitor or other device even while operating on auxiliary power.
